r0 -ALL wnon IT MAY concnnn;

Be it known that THOMAS L. BAYLIBS, oi the city of Richmond, and State of Indiana, have invented a. new and useful Improvement in Inking-Apparatus; andI do hereby declare that, the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which-- figure 1 is aperspective view.

colors.

To enable others skilled iu'the art to make and use my invention,I will proceed to describe its construction and operation.

A and A represent the sides of the structure, framed together with beams g.

B is a rotating cylinder, supported on shaft J, the latter having jurnahbearings in sides A.

My invention rolates'to an apparatus to bc'uscrlin connection withprinting-preeses for inking in different D and E each represent a set of metallic inking-bars, secured on the'surfaccpf eylinderB, and on lines parallel to the circumference of the latter.

0 and C are inking-rollers. I F and F are type-rollers. The curved inking-bars and E are made to conform in shape to the circumference of cylinder 13, and are provided at their ends with barb-shaped hooks, by means of which they are secured to said'cylinder. Cylinder I is provided with a, dove-tailed channel, P, across its circumference, into which one end of each eurved'ba-r, I) and E, is hooked, as shown in fig. 3. The opposite ends of said bars are hooked on transverse bars 0 and e, which bars are pivotedat n in radial bars aand a. The latter are pivoted at (1, near sheft'J, on its end of cylinder 13. The bars a and c are situated in a transverse recess, It, across the circumference of cylinder 13, opposite channel I, the depth of which recess is equal the thickness'of bars a.

(fund d represent \/-shapcd lugs, attached to the ondsof cylinder B, centrally of the recess 71. The bars rt and a are secured by screws 16 (or in any suitable manner by which they may be readily attached) to lugs (Z and d, thus tightening bars 6 and e, by which the inking-bars are held.

When barsa'n nd a are detached from lugs d and d, the transverse bars 2 and c are permitted to move on the surfacc of cylinder B, between lugs ii and the edges of recess 7:, thus allowing the inking-bars D and E to be readilynpplied to and taken from cylinder B.

The inncr'sides of bars e and e are bevelled to suit the barb-shaped hooks at-the ends of the inking-bars, by which the latter are secured.

Flexible strips, S, of rubber, or other suitable material, are inserted along the bevelled edges of bars e and a and sides of channel P, on which the inking-bars are hooked,-the purpose of'said flexible strips being to com pensate for any variation in length that may occur in said inking-bars.

The bars D and E are arranged, with their colors, alternating across cylinder B, and each set is inked in different colors by rollers O and C. The roller 0 has its bearings in the upright bars I, and roller G has its bearings iii-tho upright bars I. The bars supporting roller C are situated within bars I, all of which bars are hinged on boit m, ncarthe bottom.

The rollers C and O! are drawn to cylinder B by rubber springs, t and t, attached to their tops and to sides A, or by springs of any kind suitably arranged.

G is a shaft, havingjournahbearings in sides A, near each end of which shaft are situated came 6 and b mass The toothed wheel V is attached to the axle of cylinder B. and toothed wheel at is attached to the journal of roller G. v I

Wheel u is provided with a handle, N, by means of which motion is given to the rotating devices of the appnratus.

The 'n'he'cgs u and V are equal in'size, and the canisb and 6' correspond relatively in length of their are to the inking-bars D and E, and are so arranged on shaft G as to eachcorrespond in, position to the set of inking-hars-currying a difl'erent-colored ink. I 1

The cams b are opposite upright bars I, end cums b are opposite bars I. Thus, asfthecylinder B and shaft G are made to rotate, the cams are brought in contact with their respective burs I and I, by which the inking-rollers C and C' are each forced back from the cylinder, while the bars carrying-. a difierent-colored ink are allon'ed to pass in contact with the roller corresponding in color, by which they are inked. Thusth'e rollers are alternately allowed to. come in contact with and ink the set of bars of corresponding color, while the roller ofdiil'erentcoloris held ofi hy the coins.

Thciu'k is applied to rollers C and Gf in any ordinary manner.

Parallel lines 1!!6 drawn around cylinder B, zit shortintervals, on its surfece, by which the bars D and E may be correctly mljusteiL,

IInringthus fully described my said invention, whpt I claim, and desire to secure by Letters Patent, is-

1. The combination of the central hub B, a series of adjustable inking-bars D E, end a clamp for securing the bars at the ends without the intervention of uny'intermediate letcrul supports, substantially as set forth.

2. Interposing rubber, or other yielding material, between the inner surface of the'hooks of bars D and E and their point of contact with cylinder B and longitudinal bars ea'nd e, for the purpose set forth.

3. The owns 6. and b, in combination with bars I and I' androllers C and C. substuntiallv as described, and for the purpose set forth.
